### Response:
assistant
Winston Churchill's Iron Curtain speech, given in 1946, focused on the political divide in Europe following World War II, warning the world of the potential consequences of a divided Europe. He proposed that the United States and the United Kingdom had a responsibility to help defend the democracy and freedom of countries in Eastern Europe, lest the area fall to communism and potentially threaten the democracies of the West. He stressed the urgency of the situation, asserting that the UK and US needed to come to the aid of Eastern Europe before it was too late.
